SPECIFICATION formingpart of Letters Patent No. 501,984, dated July 25, 1893.

Application filed May 12, 1893- Serial No. 474,010. (No model.)

To all whom it may concern.-

Be it known that I, J osnrnus WYLIE, a citizen of the United States, residing at Ireland Hill, in the county of Marion and State of Alabama, have invented a new and useful Churn, of which the following is a specification.

The invention relates to improvements in churns.

The object of the present invention is to improve the construction of that class of churns which employ vibrating or reversely-rotating churn-dashers, and to enable any slack of the belt to be taken up and at the same time to maintain the vibrating shaft perfectly plumb.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings: Figure 1 is a perspective view of a churn constructed in accordance with this invention. Fig. 2 is a vertical transverse sectional view. Fig. 3 is a vertical longitudinal sectional view.

Similar numerals of reference designate corresponding parts in the several figures of the drawings.

1- designates vertical parallel uprights of a supporting frame, having their lower ends secured to a brace 2, and their upper ends connected by a longitudinally-adjustable top-bar 3. The uprights are connected at their centers by upper and lower intermediate horizontal bars L and 6, provided at one side of the frame with open bearing recesses 6 and 7,

receiving a detachable dasher-shaft 8, which carries a dasher 9 at its lower end. The dasher-shaft has its upper end squared and is detachably secured to a pulley 10, which is connected by a belt 11, of stout cord, with a pulley 12, of a vibrating shaft 13. The vibrating drive shaft 13 is reversely rotated by an operating-lever 14, having its rear end fulcru med on a post 15, and provided intermediate of its ends with an opening 16, and laterally-extending arms 17, arranged on opposite sides of the vibrating shaft and connected therewith by a cord 18, or its equivalent. The cord 18 passes through a perforation 19, of the vibrating shaft and has its ends secured to the arms 17; and as the operating-shaft is raised and lowered the sides of the cord 18 are alternately wound and unwound around the vibrating shaft 13. A balance-wheel20 is mounted on the vibrating shaft near the top thereof to render the motion continuous and to prevent the vibrating shaft stopping at the end of the stroke. The belt 11 is wound around eachof the pulleys several times,in order to obtain a firm hold to prevent slipping, as the shafts are vibrated very rapidly to effect a rapid production of butter; and in order to take up any slack of the belt 11 to maintain the belt at, the desired tonsionthe lower end of the vibrating shaft 13 is journaled on an adjustable slide 21, and the upper end of the shaft 13 is journaled in a bearing-opening of the longitudinally-adjustable top-bar 3. The lower end of the shaft 13 is provided with ajournal which is arranged in a bearing-socket 22, of the slide 21; and the latter is slidingly mounted in a longitudinal recess 23 in the upper face of the lower intermediate cross-bar 5. The slide 21 is provided with a longitudinal opening 24, adapted to partially register with an opening 25 of the cross-bar 5, and to be forced into more complete registering by a wedge 26. The wedge 26 is adapted to move the slide away from the dasher-shaft in tightening the belt, and its vertical edge engages a transverse piece 28, which is secured to the upper edges of the bar 5, spanning the recess thereof. The beveled edge of the wedge engages the outer end of the opening 24 of the slide, and as the Wedge moves downward the slide is forced outward, as will readily be seen. The upper intermediate cross-bar 4 has an elongated shaft-opening 29, to permit free movement of the vibrating shaft in its adjustment, and it has a longitudinal slot 30 to receive the upper end of the wedge, when the latter is in its most elevated position when the belt is first placed on the pulleys, in order to steady and support the wedge. The upper ends of the uprights 1 are reduced, and the top-bar 3 is provided with longitudinal slots 31, and has at the inner ends of the slots adjusting perforations 32, arranged at different distances from the slotsand adapted to be engaged by hooks 33, which are hinged to the reduced ends of the uprights 1, and which secure the bar 3 in its adjustment. The bar 3 enables the upper end of the vibrating shaft to be adjusted to agree with the adjustment of the lower end in order to maintain the vibratingshaftperfectlyplumb to insure proper operation of the vibrating mechanism. The post 15 is arranged in rear of the front portion of the frame and is connected with the uprights 1 by upper and lower forwardly-diverging braces 34 and 35.

It will be readily apparent that the churn is simple in construction, that the dasher may be rapidly vibrated to accomplish a rapid production of butter, and that the belt connecting the pulleys may be maintained atthe desired tension and the vibrating shaft be held perfectly plumb to insure proper operation of the parts.

Changes in the form,'proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this inventlon.

The bearing-socket of the adjustable slide is formed in a metal plate which is set in a recess of the slide.- the recess of the lower intermediate bar by the transverse piece.

In a churn, the combination of a supporting frame, a dasher-shaft journaled therein, a drive-shaft journaled on the frame, pulleys pulleys, a horizontally adjustable top bar mounted on the frame and receiving the upper end of the drive-shaft, a horizontally-adjustable slide having the lower end of the shaft journaled on it, and means for holding as and for the purpose described.
